Description


Teemu Salmela has discovered a vulnerability in ELinks, which can be exploited by malicious people to expose sensitive information and manipulate data.

The vulnerability is caused due to an error in the validation of "smb://" URLs when ELinks runs smbclient commands. This can be exploited to download and overwrite local files or upload local files to a SMB share by injecting smbclient commands in the "smb://" URL.

Successful exploitation allows exposure of sensitive information or manipulation of data, but requires that the user visits a malicious "smb://" URL or gets redirected to such an URL by a malicious URL, and that the user has the smbclient program installed.

The vulnerability is confirmed in version 0.11.1. Other versions may also be affected.


Solution:
Update to version 0.11.2.

Provided and/or discovered by:
